Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of vertical process center fixture for processing the uniform hole of bearing block as illustrated in fig. 1 and 2, including positioner
And clamping device, described positioner includes base 1, positioning step axle 2 and radial screw 4；The center of described base 1 is provided with recessed
Groove；Described positioning step axle 2 is consisted of integrative-structure, the end, location circle by cylinder in location end cylinder, location outside cylinder and location
In post, location outside cylinder and location, the external diameter of cylinder is sequentially reduced；Cylinder at the bottom of the location of described positioning step axle 2 embeds base 1
Groove in and be fixed on base 1 by fixing screw 10；Workpiece 3 it is cased with, in described location on the external cylindrical surface of described location
The face of cylinder is provided with the radial screw bore suitable with radial screw 4；The end face of cylinder at the bottom of described location and location outside cylinder pair
Workpiece 3 positions, and limits 5 degree of freedom of workpiece 3, and workpiece 3 is further positioned by described radial screw 4, limits
Workpiece 3, around the rotary freedom at positioning step axle 2 center, limits 6 degree of freedom of workpiece 3 altogether, meets the uniform hole count of workpiece 3
The positioning requirements of control processing；
Described clamping device includes opening pressing plate 5, binding nut 6 and studs 7, hangs down in one end of described studs 7
Directly it is fixed in the upper surface of the interior cylinder in location in the heart；Described opening pressing plate 5 is placed on workpiece 3 through studs 7, described
Binding nut 6 is tightened against the other end of studs 7, and the external diameter of binding nut 6 is more than the A/F of opening pressing plate 5；Use
Spanner realizes binding nut 6 and to the clamping of workpiece 3 and unclamps, and the hatch frame of opening pressing plate 5 substantially reduces binding nut 6 and presss from both sides
Impulse stroke that is tight and that unclamp, it is achieved the quick despatch of workpiece 3.
In order to make opening pressing plate 5 realize more rapid and position accurately, described fixture also includes at least two spacer pin 8,
One end of described spacer pin 8 is perpendicularly fixed on the upper surface of the interior cylinder in location, and spacer pin 8 is respectively positioned on the opening of opening pressing plate 5
Side also contacts with two parts up and down of opening pressing plate 5.
In order to save processing cost and make that positioning step axle 2 is stronger to be fixed on base 1, described fixing screw 10 is
On three and cylinder end face at the bottom of being evenly distributed on the location of positioning step axle 2.
Described fixture is fixed on three shaft vertical machining center workbench by parallel jaw and cushion block.
Before processing, the groove of base 1 put into by the first location end cylinder by positioning step axle 2, then by fixing screw
10 pairs of positioning step axles 2 are further fixed, thus realize the positioning step axle 2 location on base 1；Again with flat mouth tiger
Pincers regular jaw vertical carries out centering, and is fixedly clamped on machining center workbench, and is clamped in by this utility model flat
On mouth vice；X, Y-axis center is carried out to cutter, with the location inner circle of positioning step axle 2 with the location external cylindrical surface of positioning step axle 2
Capital face carries out Z coordinate axle to cutter, sets up the benchmark zero point of tool sharpening motion.
Then, workpiece 3 is enclosed within the location external cylindrical surface of positioning step axle 3, makes the radial direction screw thread in the outside cylinder of location
Radial screw bore on hole approximate alignment positioning step axle 2, slightly screws in the radial direction screw thread on positioning step axle 2 by radial screw 4
Hole, thus realize being properly positioned of workpiece 3；Opening pressing plate 5 opening is placed on workpiece 3 through studs 7, and pushes limit to
The direction of position pin 8, two spacer pins 8 and studs 7 determine the exact position of opening pressing plate 5, use spanner dextrorotation
Turn binding nut 6 and compress opening pressing plate 5, thus realize the Quick-clamped of workpiece 3, and then ensure that bearing block will not be along with processed
Journey and loosen, and then guarantee its invariant position, thus ensure the machining accuracy in uniform hole.
